... clearly we're not all getting the full conversation here ... but in any
event, one of the functions of the Motronic system is that right after the
engine is shut off, the computer runs high current through the wire to heat
it to 1800 degF for one second to burn off any such accumulation.  

I also sent Arun a direct e-mail noting that I remember a post stating that
there was a company that rebuilt MAF Sensors.  Anyone got that reference
handy?
